  • Beschreibung: Riverine export into the ocean contributes greatly to global microplastic (MP) contamination, yet little is known about the dynamic variation of MP in the water columns of estuarine systems. To increase our understanding of this process, we sampled during four seasons at ebb and flood tides the saltwater intrusion node of the Yangtze River Estuary, covered the dry and wet seasons. According to the seasonal abundance of MP, its vertical distribution, and current velocity to calculate the full water column MP net flux. Also, a tide-model microplastics residual net flux were used to estimate Yangtze River MP flux in 2017–2018. We observed that discharge and upstream currents collision contribute to the high MP concentration and that the mean MP abundance fluctuated with tidal flooding and ebbing. Our study suggests that riverine MP flux can be overestimated due to reciprocating current carried MP from the estuary. Using the tidal and seasonal variation in MP distribution, we calculated a tidal impact factor index (TIFI) for the Yangtze River Estuary that is between 38.11% and 58.05%. In summary, this study provides a baseline of MP flux research in the Yangtze River for similar tidal-controlled rivers
